In construct 2, when a layout extends past the viewport boundaries, viewport limits where shown as a box. This function seem stop be absent from C3. Also, it seem to be impossible to zoom the stage. Am I missing something or are really these options absent from C3 ?

Thanks Ashley, Unfortunately, these functions don't seem to show on Chrome for MacAs for the zooming function for the scene, bottom of window shows "Zoom : 100%" but I can't find anywhere + or - buttons.
